BATTERY TYPES AND SETTINGS
ZAFIR 200 can easily be set for different types of batteries or conditions. The following recommendations should, however, only be
seen as guidelines. Please consult the battery manufacturer for further instructions.
Settings are made by pressing the “MODE-button “ and stepping forward one press at a time until the required mode is reached, the
button is then released. After about 2 seconds the charger activates the selected mode. The selected mode is saved in a memory in
the charger and remains there even if the charger is disconnected from battery and mains.
NORMAL
NORMAL - Normal setting for wet batteries, maintenance free and for most Gel batteries. Some Gel batteries
prefer a slightly lower charging voltage. Please consult the battery manufacturer when in doubt.
NIGHT
NIGHT – This mode is equal to NORMAL, but with reduced current. The built-in fan is disabled and the unit is
almost silent. The Unit returns automatically to NORMAL after 8 hours. To ensure that the charger restarts in
NIGHT mode in the event of a power failure the setting is stored in a memory. The indication shows “NIGHT”
even if the charger has returned to NORMAL mode to remind that the charger will start in NIGHT mode next time.
RECOND
RECOND - This mode is used to recover deep discharged flooded batteries where you could expect a stratified
acid (high acid weight in the bottom, low on top). Check with battery manufacturer when in doubt.
Use this mode with care, because the high voltage will cause some water loss. 16V is normally no problem
for electronics in 12V system. Consult your supplier when in doubt. Life of light bulbs will be reduced at higher
voltage. Try to disconnect light from the battery during this phase. Maximum effect and minimum risk for
electronics is achieved by charging a disconnected battery.
CHARGING PHASES
ZAFIR 200 charges and analyses in eight fully automatic steps. ZAFIR 200 has three different operating modes, see Battery Types
and Settings.
The battery charger has an 8-step fully automatic charging cycle:
Desulphation
Desulphation with pulses recovers sulphated batteries. Indicates with lamp 1.
Soft start (Lamp 1)
Start mode for the charging cycle. The start phase continues until the battery’s terminal voltage has risen above the set limit, at which
point the charger switches to bulk charging. If the terminal voltage has not passed the voltage limit within the time limit, the charger
switches to fault mode (lamp 0) and discontinues the charging. If so, the battery is faulty or its capacity is too large.
Bulk (Lamp 2)
Main charge when 80% of charging takes place. The charger delivers maximum current until the terminal voltage has risen to the set
level. Bulk has a maximum time, at which point the charger automatically switches to Absorption.
Absorption (Lamp 3)
Complete charge up to virtually 100%. The terminal voltage is maintained at the set level. During this phase the current tapers
successively. Once the current has tapered to the set limit, this phase switches to being timed. If the total time for Absorption exceeds
the time limit the charger automatically switches to maintenance.
Analysis (Lamp 3)
Testing self-discharge. If self-discharge is too high, charging is discontinued and fault mode is indicated.
Maintenance charging - Float (Lamp 4)
Charging at constant voltage.
Maintenance charging - Pulse (Lamp 4)
Charging varies between 95% and 100% state of charge. The battery receives a pulse when the voltage drops and keeps the battery
in perfect condition when it is not in use. The charger can be connected for months at a time. The charger continuously measures the
terminal voltage to determine whether a charging pulse should be initiated. If the battery is loaded and/or the battery’s terminal voltage
drops the charger starts a charging pulse until the terminal voltage reaches the set level. The charging pulse is then discontinued and
the cycle is repeated infinitely. If the terminal voltage drops below a lower limit, the charger automatically goes back to the beginning
of the charging curve.
Recond (Lamp 5)
This mode is used to recover deeply discharged flooded batteries. Recondition of deep discharged batteries. The voltage increases
with reduced current for a limited time period. The higher voltage starts some gassing and mixing of the acid, which is beneficial for
both battery capacity and expected life. Note that the battery could emit explosive gas during Recond. Recond is performed between
Analysis and Maintenance.
